Abstract
The invention relates to an automatic detection method for maturity of cotton linters. After the cotton linter sample is processed, the fiber wall thickness and the wall-cavity ratio are automatically detected by a multifunctional fiber instrument, and the maturity of the cotton linter is judged by the ratio of the cell wall thickness to the maximum cell width. The method avoids subjective errors of judgment of the appearance shape by artificial observation, and is accurate and easy to control; the slicing technology and the electronic detection technology are effectively integrated, so that the accuracy and timeliness of detection are improved, and the time is further shortened; the fiber is not damaged in the treatment process, and the accuracy of the detection result is improved.
Description
Technical field
The present invention relates to a kind of automatic testing method of cotton linter degree of ripeness.
Background technology
Detecting the cotton linter degree of ripeness at present mainly is manual analysis; Key step is: with alcohol processing → sodium hydroxide solution soak the washing of expansions → clear water to neutral → Congo redly boil that dyeing → with the observation of dissecting needle microslide composings → microscopically, the full rod-like fibre that is nothing commentaries on classics song is judged as mature fibers.
There is the long defective such as production control that influences personal error accuracy, detection time big, that the destruction of fiber influenced testing result in this manual analysis.
Cotton fiber is in growth course, and the fiber of primary growth forms the circular tubule of thin-walled, is full of protoplasm in the pipe, the synthetic therein cellulose that is deposited in the cell membrane.When secondary wall was thickeied gradually, cell just dwindled gradually.So ripe cotton fiber cell is less; Otherwise jejune cell is then bigger.
Whether fibrocellular full shape and maturation can be measured through the fiber square section; After fiber soaked into sodium hydroxide solution, the size of the thin and thick of fiber finer cell wall, cell dia ratio was to judge fiber maturation whether method.
Cellulosic instrumental analysis existing application in fibre length, fibrocyte classification and Detection arranged now, be mainly used in the fiber observation experiment of pulp and paper pulp, but also be not used in the detection of cotton linter degree of ripeness.For further dwindling personal error and detection time, automatic assay is carried out in detection to the cotton linter degree of ripeness.
Summary of the invention
The present invention is intended to solve prior art problems; Overcome the long defective that influences production control of accuracy, detection time that its personal error is big, the destruction of fiber influenced testing result; Provide that a kind of error is little, can not destroy fiber, detection time short, utilize apparatus measures fibrocyte wall thickness, cell dia ratio to judge the automatic testing method of cotton linter degree of ripeness.
In order to realize the foregoing invention purpose, its concrete technical scheme is following:
A kind of automatic testing method of cotton linter degree of ripeness is characterized in that: may further comprise the steps:
A, make the cotton linter sample in order arrangement by same direction with dissecting needle, unidirectional number of fiber number percent is 60-80%, is fixed on then on the food slicer, and it is solidified, and dries;
B, with the sample of blade removal surface, downcut sample to be checked then fast;
C, be placed on the sample to be checked that downcuts on the microslide, at first dropping sodium solution soaks sample and expands, and drips the congo red staining agent again, and dyeing covers the pressure slide;
D, be put into multifunctional fibre appearance CD-ROM drive place to sample to be checked, amplify 600-700 doubly, get into and measure, click fibre wall thickness and wall chamber ratio, measure;
E, measurement result is carried out the judgement of degree of ripeness according to cell wall thickness and cell breadth extreme ratio.
Food slicer described in the above-mentioned steps A is a Kazakhstan formula food slicer.
Sample is solidified in being solidified as with the pure collodion of the analysis of mass percent concentration 5.0% described in the above-mentioned steps A, solidifies the back air-dry 12-18 minute.
The sample on the surface described in the above-mentioned steps B and the cutting method of sample to be checked are adjacent to formula section sample place, Kazakhstan for become 15 degree angles with blade; The sample of the quick removal surface of one cutter; And then be close to Kazakhstan formula slice surface with same gimmick, a cutter downcuts sample to be checked fast.
Doubly clear down to manifest crosscut planar amplifying 600-700 for the sample of the cutting-out described in the above-mentioned steps B.
The concrete operation method of above-mentioned steps C is: at first drip 1-2 and drip the sodium hydroxide solution that mass percent concentration is 17.5-18.5%; Sample was soaked expansion 2-3 minute; Drip 1-2 again and drip the congo red staining agent that mass percent concentration is 1.0-2.0%; Dyeing covers the pressure slide, inhales with filter paper and unloads unnecessary coloring agent in slide edge and sodium hydroxide solution.
Cell wall thickness described in the above-mentioned steps E and cell breadth extreme ratio greater than 1: 3 be the ripe cotton short flannel.
The useful technique effect that the present invention brings: adopt advanced instrument to carry out the measurement of cell wall, cell wall thickness and cell breadth extreme ratio are mature fibers greater than 1/3rd, and utilize computing machine to add up into map analysis automatically.
The useful technique effect of this fibre maturity assay method is:
1, the subjective error of having avoided artificial observation face shaping to judge, accurately, be easy to control;
2, microtomy and electric detective technology efficient set, improved the accuracy, the promptness that detect, the time further shortens.
3, can not damage in the processing procedure, improve the accuracy of testing result fiber.
